Meaning
The flag is set when the CONFIGURED configuration and the ACTUAL configuration
match.
The flag is set when an AS-i slave with address 0 is present. (List of Detected Slaves)
The flag is set if automatic address programming is possible. This means that
AUTO_ADDR_ENABLE = 1 and no "incorrect" AS-i slaves are connected to AS-Interface.
The flag is set if automatic address programming can be performed. This means that one
AS-i slave has failed.
The flag is set in "configuration mode" and reset in "protected operation".
The flag is set when the AS-i master is in "protected operation".
The flag is set when the voltage on the AS-i cable is too low (AS-i Power Fail).
The flag is set if the offline phase is active.
The flag is set if none of the AS-i slaves signal a peripheral fault.
The "Data_Exchange_Active" flag is set when cyclic data exchange is in "protected
operation".
The flag is set if the "OFFLINE" operating status is to be adopted or has already been
adopted.
The flag indicates whether automatic address programming is disabled (BIT = 0) or
enabled (BIT = 1) by the user.
The flag is set if a ground fault has been detected on the AS-i cable.
The flag is set if the test of the internal EEPROM was successful.
The flag indicates whether ground fault detection is enabled (BIT = 0) or disabled
(BIT = 1) by the user.
